How to use a solid drying agent?

Solutions

Expert Solution

The organic solvent containing organic compounds should be first washed with saturated brine solution to remove most of the water from it.

Thereafter, put the organic layer in a conical flask of relatively larger size. Then using spatula put small portions of anhydrous sodium sulfate (Na2SO4) or anhydrous Magnesium sulfate (MgSO4) and manually swirl the solution vigorously. Then again add small portion of the anhydrous salt and swirl. Keep adding and repeating the procedure, till you observe that the added salt (Na2SO4 or MgSO4) do not stick to each other and they settle down in the base of conical flask not as a lump, but as dry powder.

After that filter off the solid salt from the solution using fluted fiter paper or buchner flask under vacuum.

Assuming a constant drying condition,a pile of meat wet solid was dried on a tray dryer.The thickness of material on the tray is 35.4 mm. Only top surface with an area of 0.45 m2 was exposed to drying. It took approximately 3.9 hours to dry 12.0 kg wet meat from its initial free moisture of 0.55 kg free moisture/kg dry meat to its critical moisture content of 0.22 kg free moisture/ kg dry meat. Evaluate the time to dry a...

A wet solid is dried from 40% to 10% moisture under constant drying conditions in 5 hours. If the equilibrium moisture content is 0.0416 kg moisture/kg dry solid and the critical moisture content is 14%, how long will it take to dry from 40% to 5% moisture under the same conditions. All percentages other than equilibrium moisture content are on wet basis. Assume linear relation between rate of drying and moisture content during falling rate period.

Drying

The maximum amount of total solids allowed in a boiler is 800 mg/L. The feed water has 10 mg/L solids. If the boiler produces 40,000 kg/hr stream, calculate the amount of water removed per hour by making a blow down.
